Let me start by aying that I've been a professional web developer since about 10 years. I dabbled in a little Java, but did most of my work first in Python, then Ruby, JavaScript and CoffeeScript. Ruby on Rails with JavaScript was OK. Clojure and ClojureScript are blowing my mind every day. So yes, I'd say it's a replacement. And not an incremental one, but something that feels solid, is fast and a lot of fun to write in. Of course this is just my personal opinion that luckily some people share. To go into detail would probably entail writing a book. But I'm definitively not going to write EcmaScript 2016+ in the future. Instead I'll follow Uncle Bob and proclaim the last programming language: https://skillsmatter.com/skillscasts/2323-bobs-last-language https://skillsmatter.com/skillscasts/2323-bobs-last-language Enjoy the talk^^
